Control System Testing & SCADA Services in Pakistan.
TransfoLine provides turnkey Control System Testing, Substation Automation, and PLC/SCADA Commissioning Services across Pakistan. We execute rigorous cold and hot loop checks, emergency trip matrix verification, safety interlocking logic validation, and protocol testing (IEC 61850, Modbus, DNP3) to ensure 100% fail-safe automated plant operation.
What is Control System Testing & SCADA Commissioning?
Control system testing is the thorough functional validation of programmable logic controllers (PLC), remote terminal units (RTU), supervisory control and data acquisition (SCADA) servers, and safety instrumented systems (SIS). It guarantees that all field sensor signals, auto-sequencing logic, safety interlocks, and emergency trip commands function flawlessly before plant energization.
End-to-End I/O Loop Verification
Every single analog input (4-20mA temperature, pressure, level transmitters) and digital output (breaker trip, pump start/stop contacts) is injected and confirmed at the SCADA screen with calibration records.
Interlock & Safety Shutdown Logic
We test mechanical and electrical interlocks (e.g. breaker-isolator interlocking, dual source auto-transfer schemes, and fire alarm emergency trips) to prevent dangerous operational sequencing errors.

Frequently Asked Questions.
Technical advice on control system commissioning.
FAT & SAT What is the difference between FAT and SAT?
Factory Acceptance Testing (FAT) tests control panels and software logic in our workshop before dispatch. Site Acceptance Testing (SAT) verifies the fully installed system on-site with actual field cabling, sensors, and switchgear connected.
TELEMETRY Can TransfoLine commission SCADA connections to DISCO/NTDC grid centers?
Yes. We configure and test RTUs transmitting real-time voltage, current, breaker status, and tap changer telemetry to DISCO (LESCO, GEPCO, K-Electric) and NTDC control centers using IEC 104 and DNP3 protocols.
